WILLIAM L. STEIN, OF NEW YORK, N. 'Y., ASSIGNOR 0F ONE-HALF TO EDWARD A.STEIN, OF NEW YORK, N. Y.

CHAN-GEABLE EXHIBITOR.

Application filed October 21, 1920.

To all whom it may concern:

Be it known that I, lViLLn-Qr L. STEIN, a citizen of the United States,and resident of the city of New York, in the county of Bronx and Stateof New York, have invented cer ain new and useful Improvements inChangeable Exhibitors, of which the following is a specification.

The present invention relates to change able exhibitors, that is to sayto display devices wherein pictures, inscriptions, etc., aresuccessively presented for observation.

One of the objects of the invention is to produce an exhibitorattachment specially designed for use in connection with pencils orpen-holders.

Another object of the invention is to provide a pencil attachment of thetype mentioned which is simple in construction, eliicient in operationand capable of being mounted upon a pencil without material changes inthe construction of the latter.

A further object of the invention is to so construct the attachment thatit does not materially increase the cost of the pencil, therebypermitting of a production of the same on a commercial scale.

With these and other objects in view, which will more fully appear asthe nature of the invention is better understood, the same consists inthe combination, arrange.- ment and construction of parts hereinafterdescribed, pointed out in the appended claim and illustrated in theaccompanying drawings, it being understood that many changes may be madein the size and proportion of the several parts and details ofconstruction within the scope of the appended claim, without departingfrom the spirit or sacriticing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated inthe accompanying drawings, in which Figure 1 is a front elevation of apencil with a changeable exhibitor, constructed in accordance with thepresent invention, mounted thereon; Fig. 2 is a section taken on line 22of Fig. 1, partly in elevation, on a larger scale; and Fig. 3 is asection taken on line 3-3 of Fig. 2.

In the drawings the numeral 10 indicates Specification of LettersPatent.

a pencil of the usual construction, including a pencil casing 11 ofwood, inclosing longitudinally a thin strip 12 of graphite or similarmaterial. To one end of the casing is attached in any suitable manner atubular body 13, in which is mounted a suitable erasmg material 14-, asusual in devices of this type. On the outer face of the tubular body 1sformed a circular projection or bead 15 iii a plane at right angles tothe longitudinal axis of the said tubular body, and above this bead thesaid tubular body bears pictures 16, preferably all around the same.These pictures may be provided upon thetubular body in any suitablemanner, for instance they may be printed thereon or they may be carriedby a flexible strip of material which is wound around the tubular bodyand secured thereto in any preferred manner. Over the tubular body isdrawn a sleeve 17, having an aperture or sight opening 18 in. alinementwith the pictures on the tubular body. The sleeve is rotatably mountedupon the tubular body,but is held thereon againstlongitudinal movement.For this purpose the said sleeve is provided in its inner face with agroove 19, in which the bead 15 is seated. The sleeve is made of sheetmetal and provided with a longitudinal slot 19 adjacent its groove, topermit of a convenient mounting thereof on the tubular body 13.

In use, the apertured sleeve is held stationary, while the characterbearing tubular body is rotated by turning the pencil casing in thedesired direction, whereby the different pictures on the said tubularbody successively appear to the observer through the aperture or sightopening 18.

It is obvious that, while herein the tubular body has been shown asbearing pictures, suitable inscriptions, memoranda, etc., may be carriedthereb Attention is ca led to the fact that the exhibitor may be mountedon pen-holders, penoils and similar devices, which serve as a handle forsaid exhibitor.

The device herein described is capable of use as an advertising medium,amusement device, general information conveying contrivance, etc.

What I claim is An exhibitor attachment for pencils, coma pencil bearingupon its outer face char- 7 esters, said tubular body being provided onits outer face With a bead in a plane at right angles to. thelongitudinal axis thereof, and a sleeve rotatably mounted upon saidtubular body having a sight opening in alinement with said characters,sald sleeve being provided in its inner face With a groove in which saidbead is seated, said sleeve being also provided with a longitudinal slotadjacent its groove to permit of a mounting thereof on said tubularbody.
